minFjollede: "my silly"

An experimental weight-surgery variant of SmolLM2-135M-Instruct, made with the HyperTensor CECI "graft" procedure. It is a research artifact: it does not outperform its base model.

What was changed

Only the layer-12 MLP was changed: W12 <- W12 + 0.5 * (Q - W12) @ P, where Q is the top-left slice ([:1536, :576] / [:576, :1536]) of the layer-12 MLP matrices of Qwen/Qwen2.5-0.5B-Instruct (whose real shapes are 4864x896 / 896x4864). The slice is cropped by row and column index and not aligned, so it is not a functional Qwen FFN. Created by scripts/graft_proof.py ("Sammensmeltning_Cross").

The other 269 of 272 tensors are bit-identical to the base model. Weights are stored in float32. The tokenizer and chat template are the base model's.

Measured quality (audit, 2026-10-09)

Teacher-forced next-token loss on 30 web and 30 code documents (512 tokens each, data/corpus/{web,code}.dev.jsonl), compared with the base model:

text base NLL this model NLL perplexity change top-1 agreement with base KL(base‖model)
web 2.865 2.885 +2.0% 91.3% 0.026
code 1.783 1.824 +4.1% 91.9% 0.045
all 2.324 2.354 +3.1% 91.6% 0.035
original HyperTensor test base this model
graft_proof 15-sentence PPL (mean of per-sentence PPL) 60.96 68.15
graft_benchmark MMLU-lite (50 items) 31/50 34/50 (+3 / -0 items, sign-test p=0.25)
graft_benchmark BoolQ (15 items) 6/15 5/15 (+0 / -1, p=1.00)

The earlier card claimed "only +7.2 PPL; definitive proof that CECI grafting works across model families". The "% recovery" figures compared this model with a copy of the base whose MLP had been zeroed. This model was never ablated, so they do not measure recovery. On real text the model is slightly worse than its base, and the small MMLU-lite/BoolQ differences are a few items out of 50/15 and are not statistically significant.

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

tok = AutoTokenizer.from_pretrained("NagusameCS/minFjollede")
model = AutoModelForCausalLM.from_pretrained("NagusameCS/minFjollede")
msgs = [{"role": "user", "content": "What is the capital of France?"}]
inputs = tok.apply_chat_template(msgs, add_generation_prompt=True, return_tensors="pt", return_dict=True)
out = model.generate(**inputs, max_new_tokens=64, do_sample=False)
print(tok.decode(out[0, inputs["input_ids"].shape[1]:], skip_special_tokens=True))
